SSPA Power Supply - Final Diode Cooling

I discovered through some recent load testing that at just a bit above 1/2 max load on the power supply the dual protection diodes I'm using get quite hot, at least 150F degrees.  So to help control that I'm going to cut up a large heat sink I have tomorrow and mount these 200 amp protection diodes on them.  I'm probably also going to add fans to the heat sinks as well.

Here are some pictures.
